Benefit–cost analyses in public health typically calculate the benefits of mortality reduction interventions by multiplying the Value of a Statistical Life (VSL) and the expected decrease in fatalities. This procedure approximates the benefits of small mortality changes but is inaccurate for large risk changes because it holds constant the VSL—a marginal rate of substitution. Building on the theoretical framework of the VSL, we derive expressions to calculate the benefits of non-marginal mortality reductions with empirically calibrated compensating variations and illustrate their use.

计算非边际死亡风险降低的经济价值

公共卫生领域的效益-成本分析通常通过将统计生命值 (VSL) 乘以预期死亡人数减少来计算降低死亡率干预措施的效益。该程序近似于较小的死亡率变化带来的好处，但对于较大的风险变化则不准确，因为它使 VSL（边际替代率）保持不变。基于 VSL 的理论框架，我们推导了表达式来计算通过经验校准的补偿变量实现非边际死亡率降低的效益，并说明其用途。
